THROW-OFF DEVICE FOB VIENNA-RGLL-FORMING MACHINES.

Application filed. Gctober 25, 1926. Serial No. 144,082

. rlhis invention relates to machines for forming Vienna rolls and particularly to an Y ries of ejecting rings associated with the forming dies and so actuated that they will j force the rolls from the dies at a given point.

An additional object is to provide an improved structure over my co-pending application, Serial No. 76,047, now Patent No. 1,625,649.

In the accompanying drawings- Figure 1 is an elevation ot' the principal part of a roll forming machine, the same being shown with an embodiment ot the in' vention applied thereto.

Figure 2 is a sectional view through Figure 1, approximately on line 2 2, the same being on an enlarged scale.

Figure 3 is aplan view ot one of the eject-v ing plates or rings.

Referring to the accompanyingdrawings by numerals, 1 indicates a standard and 2 a pulley adapted to carry the belt 3 which carries the roll supporting cups 4. The pulley 2 is rotated through the action ot a train of gears 5 actuated by a suitable source of power, as :tor instance, an electric motor 6. The train of gears 5 operate the large gear 7 which is connected with pulley 2 whereby said pulley is actuated. The large gear 7 meshes with a second large gear 8, which second gear is of the same diameter as gear 7 and, consequently, moves the pulley structure 9 at the same speed as pulley 2. The parts just described are similar to certain arts in my patent No. 1,625,649 and, there ore, will not be further described.y It will also be understood that a second pulley similar to pulley 2 is provided to assist in Supporting belt 3, the same being fully disclosed in my patent heretofore mentioned.

- In the presentY application, the` invention resides in the association of parts and the particular construction involving means for forcing from the various dies 10 the rolls after they have been acted upon by the dies. Itis to be noted that .at some desired point, batches of dough are placed in the cups 4 and as they are moved to a pointV above the pulley 2, one

of the dies 1() enters the cup and cuts or presses the dough into the desired shape. Usually thisoperation causes the dough to adhere to the die and, consequently, the same must be removed by the hand or some mechanism must be provided' in order that the machine may worlrl contimially.V Y In the accompanying drawings, ejecting means have been provided for ejecting or throwing off the rolls from the dies 10. This mechanism includes a .throw-off plate 11 shown in detail in Figure 3. From Figure 2 it will be noted that the cups 4 are arranged in pairs and dies 10 are also arranged in pairs so-that the plate 11 is provided with a pair ot' openings, namely, openings 12 and13. These openings are of the proper shape to lit the various blades of the dies 10 whereby the plate 11 may be moved radially back and forth. It is, of course, evivdent that one row of cups 4 could be used or even more than two rows and the device would operate equally well. A reciprocating rod 14 is secured to the plate 11 by a suitablenut 15 and adjacent the'point where the plate 11 is secured to rod 14 is arranged a spring 16 sur rounding rod 14 and acting on the pulley 9 and on the plate 11 to tend to normally move the plate 11 outwardly. The rod 14 reciprocates in a suitable groove 17 in a plate 18 secured in any desired manner to the central web 19 ot pulley 8. Near the inner end 'oi' rod 14 a stub shaft 20 is connected with the rod and on this stub shaft is mounted a wheel 21 which engages the inner face of the cam 22 whereby as the pulley 9 and associated parts rotate the rod 14 will be pulled inwardly at a given point and then forced outwardly by spring 16. It will be understood that the description of one rod 14 and associated parts will apply equally to all of these rods as there is provided a rod 14 for each pair of dies 10 and they all co-act with the same cam 22. It will be noted that cam 22 is formed with an arc-shaped section 23 which is provided with a sudden rise 24 and then a gradual lowering portion 25. Wlhen the various wheels 21 are operating on the arc-shaped portion 23, the various plates 11 are held in their innermost position but as soon as any particular wheel 11 reaches the rise 24, the spring 16 associated with that particular plate 11 will quickly force the plate 11 and associated parts to an outer position and thereby quickly throw otl' thev roll which has been carried by that particular die 10. If desired, after the roll has been thrown olf, butter or other oleaginous material they be appliedv to the outer end of the die in kanysuitnble manner, as for instance, by ,a brush 26.

secured by a pin 29 to the plateBO whiehis bolt-ed to one of the standards l. An oil cup 3l is carriedbyQthe hollow vshaft 27 and `oil romthis @up is adapted to pass through suitf able epertures'32'so as to lubiicate the hollow han 27.'
